Display PHP errors on web page

So you don't have to troll logs when your web page doesn't display what is expected, copy and paste this to the top of your PHP code.

ini_set('display_errors', 1);
ini_set('log_errors', 1);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
error_reporting(E_ALL);

You will probably want to remove it once in production.

Mikrotik Bridge Horizon

To achieve similar functionality to Cisco's private VLANS, where all ports are on the same L2 segment, but cannot exchange packets, you can use Mikrotik's Bridge Horizon feature. Basically, every port in a bridge is assigned a horizon value, and RouterOS will only forward frames to other interfaces in the bridge that have different horizon values. This means that you assign the same horizon value to the interfaces that you don't want to be able to communicate. For example, you want to bridge all your customers and use a single /24 subnet and the same gateway. Typically this is bad and poses a huge security risk, not to mention performance issues. If you assign the same horizon value to the customer interfaces, then the router will not forward traffic between customers. Customer A will not be able to ping Customer B. If you had a server, such as an IP-PBX that all customers needed to access, and you were lazy and added it to the bridge, then you would assign a diff...

DHCP option 121

http://tools.ietf.org/html/rfc3442 This is used to add a classless static route to the DHCP clients. To add option 121 to a Mikrotik DHCP server, it's value is specified in HEX. The format is as follows. 0xnnddddddddgggggggg where n=mask, d=destination, g=gateway. To convert ip address to HEX, you convert each octet, so 192=C0, 168=A8, 55=37, 1=01 You can use a tool such as http://www.miniwebtool.com/ip-address-to-hex-converter/?ip=192.168.55.1 Example: To add a route to the destination network of 192.168.55.0/24 via gateway 172.16.10.1. /ip dhcp-server option add name=classlessroutes code=121 value=0x18C0A837AC100A01 where 18 is 24 in hex. *note: depending on the subnet mask, you may only need to specify 0-4 octets. In fact only the non-zero, or network portion of the subnet. Here is a table from the RFC. subnet mask Number of octets 0 0 1- 8 1 ...

System History and the undo command

The history of system configuration changes is held until the next router shutdown. The invoked commands can be 'undone' using the /undo command. By invoking the command several times, the configuration changes can be 'undone' in reverse order they have been invoked. Use the /system history print command to see the list of performed actions: [MikroTik] system history> print Flags: U - undoable, R - redoable, F - floating-undo ACTION BY POLICY U nat rule changed admin write U nat rule changed admin write ...
